❓ Frequently Asked Questions

How much do CRM integrations cost?

Native CRM integrations are typically free. Third-party platforms like Zapier cost $20-100/month depending on usage. Custom API integrations cost $5,000-50,000+ for development plus ongoing maintenance.

Are CRM integrations difficult to set up?

Native integrations take 5-30 minutes with no technical skills required. Zapier/Make workflows take 1-4 hours to configure. Custom API integrations require developer resources and 2-12 weeks depending on complexity.

What happens if an integration breaks?

Most platforms provide error notifications and logs. Native integrations auto-update. Third-party platforms usually auto-retry failed syncs. Have a process to review error logs weekly and test integrations after major CRM updates.

Can I integrate multiple CRMs?

Yes, but not recommended. Running multiple CRMs creates data silos and confusion. If you have multiple CRMs (e.g., due to acquisition), use integration platform to sync data while you consolidate onto single platform.

🎁 Final Recommendations

Start Simple: Use Native Integrations

Begin with your CRM's native integrations for email, calendar, and key tools. These are free, well-supported, and cover 80% of common needs.

Scale Smart: Add Integration Platform

When you need custom workflows, start with Make.com ($9/month) or Zapier ($20/month). These handle complex multi-step automations without coding.

Go Custom: Build API Integrations

Invest in custom API integration only when native options don't exist and business process is mission-critical. Budget $10K+ for development and $2K+/year for maintenance.

Our Recommendation:

Use native integrations for common tools (free). Add Make.com for custom workflows ($9-99/month depending on volume). Reserve custom API development for proprietary systems or unique requirements. This balanced approach delivers 95% of integration benefits at 20% of custom development costs.
